Mediterranean Sea
–
The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water. The name Mediterranean is derived from the Latin mediterraneus, meaning inland or in the middle of land and it covers an approximate area of 2.5 million km2, but its connection to the Atlantic is only 14 km wide. The Strait of Gibraltar is a strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Gibraltar. In oceanography, it is called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere. The Mediterranean Sea has a depth of 1,500 m. The sea is bordered on the north by Europe, the east by Asia and it is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, the seas average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km. The Mediterranean Sea, including the Sea of Marmara, has an area of approximately 2,510,000 square km. The sea was an important route for merchants and travelers of ancient times that allowed for trade, the history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. In addition, the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri, the term Mediterranean derives from the Latin word mediterraneus, meaning amid the earth or between land, as it is between the continents of Africa, Asia and Europe. The Ancient Greek name Mesogeios, is similarly from μέσο, between + γη, land, earth) and it can be compared with the Ancient Greek name Mesopotamia, meaning between rivers. The Mediterranean Sea has historically had several names, for example, the Carthaginians called it the Syrian Sea and latter Romans commonly called it Mare Nostrum, and occasionally Mare Internum. Another name was the Sea of the Philistines, from the people inhabiting a large portion of its shores near the Israelites, the sea is also called the Great Sea in the General Prologue by Geoffrey Chaucer. In Ottoman Turkish, it has also been called Bahr-i Sefid, in Modern Hebrew, it has been called HaYam HaTikhon, the Middle Sea, reflecting the Seas name in ancient Greek, Latin, and modern languages in both Europe and the Middle East. Similarly, in Modern Arabic, it is known as al-Baḥr al-Mutawassiṭ, in Turkish, it is known as Akdeniz, the White Sea since among Turks the white colour represents the west. Several ancient civilisations were located around the Mediterranean shores, and were influenced by their proximity to the sea. It provided routes for trade, colonisation, and war, as well as food for numerous communities throughout the ages, due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history. Two of the most notable Mediterranean civilisations in classical antiquity were the Greek city states, later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum

Sea
–
A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, the sea is the system of Earths salty. The sea moderates Earths climate and has important roles in the cycle, carbon cycle. Although the sea has been traveled and explored since prehistory, the scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. Owing to the present state of continental drift, the Northern Hemisphere is now equally divided between land and sea but the South is overwhelmingly oceanic. Salinity in the ocean is generally in a narrow band around 3. 5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers. About 85% of the solids in the sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature, surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses, former changes in sea levels have left continental shelves, shallow areas in the sea close to land. The most diverse areas surround great tropical coral reefs, whaling in the deep sea was once common but whales dwindling numbers prompted international conservation efforts and finally a moratorium on most commercial hunting. Life may have started there and aquatic microbial mats are generally credited with the oxygenation of Earths atmosphere, the sea is an essential aspect of human trade, travel, mineral extraction, and power generation. It is the scene of activities including swimming, diving, surfing. However, population growth, industrialization, and intensive farming have all contributed to marine pollution. Atmospheric carbon dioxide is being absorbed in increasing amounts, lowering its pH in a known as ocean acidification. The shared nature of the sea has made overfishing an increasing problem, both senses of sea date to Old English, the larger sense has required a definite article since Early Middle English. Seas are generally larger than lakes and contain salt water, while the defining elements of size and being bounded are generally used, there is no formally accepted technical definition of sea among oceanographers. In international law, the United Nations Convention on the Law of the Sea states that all the ocean is the sea. Earth is the known planet with seas of liquid water on its surface, although Mars possesses ice caps

Russia
–
Russia, also officially the Russian Federation, is a country in Eurasia. The European western part of the country is more populated and urbanised than the eastern. Russias capital Moscow is one of the largest cities in the world, other urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a range of environments. It shares maritime borders with Japan by the Sea of Okhotsk, the East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, in 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus ultimately disintegrated into a number of states, most of the Rus lands were overrun by the Mongol invasion. The Soviet Union played a role in the Allied victory in World War II. The Soviet era saw some of the most significant technological achievements of the 20th century, including the worlds first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the second largest economy, largest standing military in the world. It is governed as a federal semi-presidential republic, the Russian economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2015. Russias extensive mineral and energy resources are the largest such reserves in the world, making it one of the producers of oil. The country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction, Russia is a great power as well as a regional power and has been characterised as a potential superpower. The name Russia is derived from Rus, a state populated mostly by the East Slavs. However, this name became more prominent in the later history, and the country typically was called by its inhabitants Русская Земля. In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus by modern historiography, an old Latin version of the name Rus was Ruthenia, mostly applied to the western and southern regions of Rus that were adjacent to Catholic Europe. The current name of the country, Россия, comes from the Byzantine Greek designation of the Kievan Rus, the standard way to refer to citizens of Russia is Russians in English and rossiyane in Russian. There are two Russian words which are translated into English as Russians

Northern Dvina River
–
The Northern Dvina is a river in northern Russia flowing through the Vologda Oblast and Arkhangelsk Oblast into the Dvina Bay of the White Sea. Along with the Pechora River to the east, it drains most of Northwest Russia into the Arctic Ocean and it should not be confused with Western Dvina. The principal tributaries of the Northern Dvina are the Vychegda, the Vaga, according to the Max Vasmers Etymological Dictionary, the name of the river has been taken from the Western Dvina River. The toponym Dvina does not stem from a Uralic language, however, possibly it is an Indo-European word which used to mean river or stream. In the Komi language, the river is called Вы́нва / Výnva from vyn power, the length of the Northern Dvina is 744 kilometres. Together with its tributary, the Sukhona, it is 1,302 kilometres long – about as long as the Rhine River in central. The area of its basin is 357,052 square kilometres – about the size of the state of Montana in the United States. The Northern Dvina basin is roughly T-shaped, the 558 kilometres -long Sukhona River flows east and joins the basin of the west-flowing Vychegda River. The combined river flows northwest into the White Sea, which it joins near the city of Archangelsk, looking more closely, the Sukhona flows east and meets the north-flowing Yug River at Veliky Ustyug. The combined stream, now called the Northern Dvina, flows north about 60 km and receives the west-flowing Vychegda at Kotlas, the Sukhona-Vychegda was an important east–west transportation route while the Northern Dvina-Yug was a north–south route. The upper Sukhona is now connected by the Northern Dvina Canal to the Volga–Baltic Waterway, the Sukhona River flows east, eventually north-east, joins the north-flowing Yug River at Veliky Ustyug and acquires the name Northern Dvina. The P157 highway connects Kostroma with Kotlas via Nikolsk and Veliky Ustyug, North of Veliky Ustyg, the highway runs on the left bank of the Northern Dvina. Shortly downstream from the confluence, the Northern Dvina is crossed by the railway connecting Konosha with Kotlas, the Northern Dvina turns northwest and receives a number of smaller rivers such as the Uftyuga and the Nizhnyaya Toyma, both from the northeast. Near the urban settlement of Bereznik, the Vaga River comes in from the south, at this point, the M8 highway which runs from Moscow through Vologda to Arkhangelsk, also enters the region. The Yomtsa or Yemtsa River join from the southeast, with the P1 highway running parallel, the Pinega River, formerly an important river route, joins from the east. Near the mouth of the Pinega, the splits into several channels. The branches rejoin and pass the modern logging town of Novodvinsk, downstream from Novodvinsk, the 900 square kilometres delta begins. In the upstream part of the delta, the port of Arkhangelsk is located

Karelia
–
Karelia, the land of the Karelian peoples, is an area in Northern Europe of historical significance for Finland, Russia, and Sweden. It is currently divided between the Russian Republic of Karelia, the Russian Leningrad Oblast, and Finland, various subdivisions may be called Karelia. Finnish Karelia was a province of Finland, and is now divided between Finland and Russia, often called just Karjala in Finnish. The eastern part of this chiefly Lutheran area was ceded to Russia after the Winter War of 1939–40 and this area is the Karelia of the Karelian question in Finnish politics. The Republic of Karelia is a Russian federal subject, including the so-called East Karelia with a chiefly Russian Orthodox population, Karelia stretches from the White Sea coast to the Gulf of Finland. It contains the two largest lakes in Europe, Lake Ladoga and Lake Onega, the Karelian Isthmus is located between the Gulf of Finland and Lake Ladoga. In the North there were the nomadic Samis, but no natural border except for huge woods, in historical texts Karelia is sometimes divided into East Karelia and West Karelia, which are also called Russian Karelia and Finnish Karelia respectively. The area to the north of Lake Ladoga which belonged to Finland before World War II is called Ladoga Karelia, White Sea Karelia is the northern part of East Karelia and Olonets Karelia is the southern part. Tver Karelia denotes the villages in the Tver Oblast that are inhabited by Tver Karelians, the Treaty of Nöteborg in 1323 divided Karelia between the two. Viborg became the capital of the new Swedish province, in the Treaty of Stolbovo in 1617 large parts of Russian Karelia were ceded to Sweden. Conflicts between the new Swedish rulers and the population of these areas led to an exodus, thousands of Karelians, including the ancestors of the Tver Karelians. The Treaty of Nystad in 1721 between Imperial Russia and Sweden ceded most of Karelia to Russia, after Finland had been occupied by Russia in the Finnish War, parts of the ceded provinces were incorporated into the Grand Duchy of Finland. In 1917, Finland became independent and the border was confirmed by the Treaty of Tartu in 1920, Finnish partisans were involved in attempts to overthrow the Bolshevists in Russian Karelia in 1918–20, such as in the failed Aunus expedition. They also wanted to incorporate the rest of Karelia into Finland and these mainly private expeditions ended after the peace treaty of Tartu. After the end of the Russian Civil War and the establishment of the Soviet Union in 1922, in 1939, the Soviet Union attacked Finland, thus starting the Winter War. The Moscow Peace Treaty of 1940 handed most of Finnish Karelia to the Soviet Union, about 400,000 people, virtually the whole population, had to be relocated within Finland. In 1941, Karelia was liberated for three years during the Continuation War of 1941 to 1944 when East Karelia was occupied by the Finns. As a consequence of the treaty, the Karelian ASSR was incorporated with the Karelo-Finnish SSR 1941–1956

It includes the Arctic archipelagos of Franz Josef Land and Novaya Zemlya, Arkhangelsk Oblast also has administrative jurisdiction over Nenets Autonomous Okrug. Including Nenetsia, Arkhangelsk Oblast has an area of 587,400 km2 and its population was 1,227,626 as of the 2010 Census. The city of Arkhangelsk, with a population of 348,716 as of the 2010 Census, is the center of the oblast. The second largest city is the nearby Severodvinsk, home to Sevmash, Plesetsk Cosmodrome is one of three spaceports in Russia. Arkhangelsk Oblast, which includes Nenets Autonomous Okrug, borders Kirov Oblast, Vologda Oblast, the Republic of Karelia, the Komi Republic, Cape Fligely in Franz Josef Land and Cape Zhelaniya in Novaya Zemlya are both located within Arkhangelsk Oblast. Arkhangelsk Oblast is located on the East European Plain, and most of it represents forested hilly landscape, the north-eastern part belongs to the Timan Ridge, a highland mostly situated east from the oblast. The Nenets Autonomous Okrug is essentially a flat tundra with several hill chains like Pay-Khoy Ridge, the Arctic islands including Novaya Zemlya and Franz Joseph Land are mountainous with glaciers and eternally snow-covered. This region has a distinct population of polar bears associated with the Barents Sea area. Almost all of the area of the Oblast belongs to the basin of the Arctic Ocean, with the rivers being Onega River, Northern Dvina River, Kuloy River, Mezen River. A minor area in the west of the Oblast, most notably the basin of the Ileksa River, drains into the Lake Onega and eventually to the Baltic Sea. A very minor area in Kargopolsky District in the south-west of the Oblast drains into the Kema River which belongs to the basin of the Caspian Sea. The area in the Onega River basin containing the biggest lakes in the oblast, such as Lake Lacha, Lake Kenozero, Lake Undozero, the tundra of the Nenets Autonomous Okrug also contains a number of bigger lakes. The river basin of the Pinega is characteristic of the karst, the White Sea coast within the Oblast is split into the Onega Bay, the Dvina Bay, and the Mezen Bay. Solovetsky Islands, as well as a number of islands, are located in the Onega Bay. The Onega Bay and the Dvina Bay are separated by the Onega Peninsula, the Mezen Bay is separated from the main body of the White Sea by Morzhovets Island. Almost all of the oblast is covered by taiga, the coniferous forest dominated by pine, spruce, large areas in the middle of taiga are devoid of trees and covered by swamps. In the floodplains of the rivers, there are meadows, a number of areas in Arkhangelsk Oblast have been designated as protected natural areas

Murmansk Oblast
–
Murmansk Oblast is a federal subject of Russia, located in the northwestern part of Russia. Its administrative center is the city of Murmansk, as of the 2010 Census, its population was 795,409. Geographically, Murmansk Oblast is located mainly on the Kola Peninsula almost completely north of the Arctic Circle and is a part of the larger Lapland region that spans four countries. Arkhangelsk Oblast of Russia lies across the White Sea, much of the oblasts relief is hilly, with the Khibiny and Lovozero ranges rising as high as 1,200 meters above sea level and stretching from west to east. The north of the oblast is covered by tundra, forest tundra prevails further south. There are over 100,000 lakes and 18,000 rivers in the oblast, the climate is harsh and unstable, due to the proximity of the Gulf Stream on one side and Arctic cold fronts on the other. Sharp temperature changes, high winds, and abundant precipitation are common throughout the year, however, the waters of the Murman Coast in the south remain warm enough to remain ice-free even in winter. The Saami, now a small minority, are the indigenous people of the region. However, Russians started to explore the shores of the White Sea as early as the 12th century, despite these early settlements, the area remained undeveloped for centuries, with the city of Murmansk being founded only in 1916. The oblast was established on May 28,1938 from Murmansk Okrug of Leningrad Oblast, the area of Pechengsky District, which was ceded to Finland by the 1920 Treaty of Tartu and gave Finland access to the Barents Sea, was recaptured by the Soviet Union in 1940. After the Paris Peace Treaties of 1947, the local Saami population was given the choice either of staying in Soviet Russia or resettling in Finland, most of them chose the second option. Since 1991, CPSU lost all the power, and the head of the Oblast administration, the Charter of Murmansk Oblast is the fundamental law of the region. The Legislative Assembly of Murmansk Oblast is the provinces standing legislative body, the Legislative Assembly exercises its authority by passing laws, resolutions, and other legal acts and by supervising the implementation and observance of the laws and other legal acts passed by it. The indigenous people of the area, the Saami, are only a minority today. As of the 2002 Census,92. 2% of the population live in urban areas. The most populous city is the Oblasts administrative center, Murmansk, other large cities and towns include Severomorsk, Apatity, Kandalaksha, Monchegorsk, and Kirovsk. It is estimated that the proportion of ethnicities in this group is the same as that of the declared group, according to a 2012 official survey 41. 4% are adherents of Rodnovery and other indigenous folk religions, and 1% are members of the Catholic Church. In addition, 28% of the population declares to be spiritual but not religious, 12% is atheist, the Murmansk Oblast is very rich in natural resources and has deposits of over 700 minerals

Arkhangelsk
–
Arkhangelsk, also known in English as Archangel and Archangelsk, is a city and the administrative center of Arkhangelsk Oblast, in the north of European Russia. It lies on both banks of the Northern Dvina River near its exit into the White Sea, the city spreads for over 40 kilometers along the banks of the river and numerous islands of its delta. Arkhangelsk was the seaport of medieval and early modern Russia until 1703. A1, 133-kilometer-long railway runs from Arkhangelsk to Moscow via Vologda and Yaroslavl, and air travel is served by the Talagi Airport and a smaller Vaskovo Airport. As of the 2010 Census, the population was 348,783, down from 356,051 recorded in the 2002 Census. The arms of the city display the Archangel Michael in the act of slaying the Devil, legend states that this victory took place near where the city stands, hence its name, and that Michael still stands watch over the city to prevent the Devils return. Vikings knew the area around Arkhangelsk as Bjarmaland, ohthere of Hålogaland told circa 890 of his travels in an area by a river and the White Sea with many buildings. This was probably the later known as Arkhangelsk. According to Snorri Sturluson, Vikings led by Thorir Hund raided this area in 1027, in 1989, an unusually impressive silver treasure was found by the mouth of Dvina, right next to present-day Arkhangelsk. It was probably buried in the beginning of the 12th century, most of the findings comprised a total of 1.6 kilograms of silver, largely in the form of coins. Jewelry and pieces of jewelry come from Russia or neighboring areas, the majority of the coins were German, but the hoard also included a smaller number of Kufan, English, Bohemian, Hungarian, Danish, Swedish and Norwegian coins. It is hard to place this find historically until further research is completed, there are at least two possible interpretations. It may be a treasure belonging to the society outlined by the Norse source material, generally such finds, whether from Scandinavia, the Baltic area, or Russia, are closely tied to well-established agricultural societies with considerable trade activity. Alternatively, like the Russian scientists who published the find in 1992, in the 12th century, the Novgorodians established the Archangel Michael Monastery in the estuary of the Northern Dvina River. Written sources indicate that Kholmogory existed early in the 12th century and it is not known whether the origin of this settlement was Russian, or if it goes back to pre-Russian times. In the center of the town that is there today is a large mound of building remains and river sand. The area of Arkhangelsk came to be important in the rivalry between Norwegian and Russian interests in the northern areas, from Novgorod, the spectrum of Russian interest was extended far north to the Kola Peninsula in the 12th century. However, here Norway enforced taxes and rights to the fur trade, a compromise agreement entered in 1251 was soon broken

Pomors
–
As early as the 12th century, explorers from Novgorod entered the White Sea through the Northern Dvina and Onega estuaries and founded settlements along the sea coasts of Bjarmaland. Kholmogory served as their town until the rise of Arkhangelsk in the late 16th century. From their base at Kola, they explored the Barents Region and the Kola peninsula, Spitsbergen, later the Pomor discovered and maintained the Northern Sea Route between Arkhangelsk and Siberia. With their ships, the Pomors penetrated to the areas of Northern Siberia. The name of the Pomors derives from the Pomorsky coast of the White Sea, the same root appears in the toponym Pomerania. The term Pomor, which in the 10th-12th centuries meant a person who lived near sea, finally in the 15th century, the people became disconnected from the sea. The sea was not a part of economy of this region. The traditional livelihoods of the Pomor based on the sea included animal hunting, whaling and fishing, the Pomor traded by sea in corn and fish with Northern Norway, which became important to both sides. This trade was so intensive that a kind of Russian-Norwegian pidgin language Moja på tvoja developed on the North Norwegian coast that was used from 1750–1920, in the 12-15th centuries, Pomore was considered an extensive colony of the state of Great Novgorod. By the early 16th century the annexation of Pomore by Moscow was completed, in the 17th century, in 22 Pomore districts the great bulk of the population consisted of free peasants. A portion of the land belonged to monasteries and to the Stroganov merchants, there were no landlords in Pomore. The population of Pomore districts was engaged in fishing, mica and salt production, although in the 21st century, some people identify as Pomor or of Pomor origin, this is a new phenomenon. The Russian Brockhaus and Efron Encyclopedic Dictionary, in its 1890-1907 edition, to date, no encyclopedia or encyclopedic dictionary refers to the Pomor as a separate ethnic group. In the 2002 census, respondents had the option to identify as Pomors, however, only 6,571 persons did so, almost all of them in Arkhangelsk Oblast and Murmansk Oblast. Like most other Russians, Pomors have traditionally been Orthodox Christians in faith, prior to the Revolution of 1917 a large percentage of Russians from Pomorje were practicing Old Believers.

Soviet Union
–
The Soviet Union, officially the Union of Soviet Socialist Republics was a socialist state in Eurasia that existed from 1922 to 1991. It was nominally a union of national republics, but its government. The Soviet Union had its roots in the October Revolution of 1917 and this established the Russian Socialist Federative Soviet Republic and started the Russian Civil War between the revolutionary Reds and the counter-revolutionary Whites. In 1922, the communists were victorious, forming the Soviet Union with the unification of the Russian, Transcaucasian, Ukrainian, following Lenins death in 1924, a collective leadership and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin suppressed all opposition to his rule, committed the state ideology to Marxism–Leninism. As a result, the country underwent a period of rapid industrialization and collectivization which laid the foundation for its victory in World War II and postwar dominance of Eastern Europe. Shortly before World War II, Stalin signed the Molotov–Ribbentrop Pact agreeing to non-aggression with Nazi Germany, in June 1941, the Germans invaded the Soviet Union, opening the largest and bloodiest theater of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at battles such as Stalingrad. Soviet forces eventually captured Berlin in 1945, the territory overtaken by the Red Army became satellite states of the Eastern Bloc. The Cold War emerged by 1947 as the Soviet bloc confronted the Western states that united in the North Atlantic Treaty Organization in 1949. Following Stalins death in 1953, a period of political and economic liberalization, known as de-Stalinization and Khrushchevs Thaw, the country developed rapidly, as millions of peasants were moved into industrialized cities. The USSR took a lead in the Space Race with Sputnik 1, the first ever satellite, and Vostok 1. In the 1970s, there was a brief détente of relations with the United States, the war drained economic resources and was matched by an escalation of American military aid to Mujahideen fighters. In the mid-1980s, the last Soviet leader, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost. The goal was to preserve the Communist Party while reversing the economic stagnation, the Cold War ended during his tenure, and in 1989 Soviet satellite countries in Eastern Europe overthrew their respective communist regimes. This led to the rise of strong nationalist and separatist movements inside the USSR as well, in August 1991, a coup détat was attempted by Communist Party hardliners. It failed, with Russian President Boris Yeltsin playing a role in facing down the coup. On 25 December 1991, Gorbachev resigned and the twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states

Black Sea
–
The Black Sea is a body of water between Eastern Europe and Western Asia, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of rivers, such as the Danube, Dnieper, Rioni, Southern Bug. The Black Sea has an area of 436,400 km2, a depth of 2,212 m. It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, the longest east-west extent is about 1,175 km. The Black Sea has a water balance, that is, a net outflow of water 300 km3 per year through the Bosphorus. Mediterranean water flows into the Black Sea as part of a two-way hydrological exchange, the Black Sea drains into the Mediterranean Sea and then the Atlantic Ocean, via the Aegean Sea and various straits. The Bosphorus Strait connects it to the Sea of Marmara, and these waters separate Eastern Europe and Western Asia. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch, the water level has varied significantly. Due to these variations in the level in the basin. At certain critical water levels it is possible for connections with surrounding water bodies to become established and it is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is a basin, operating independently of the global ocean system. Currently the Black Sea water level is high, thus water is being exchanged with the Mediterranean. The Turkish Straits connect the Black Sea with the Aegean Sea, and comprise the Bosphorus, the Sea of Marmara, the International Hydrographic Organization defines the limits of the Black Sea as follows, On the Southwest. The Northeastern limit of the Sea of Marmara, a line joining Cape Takil and Cape Panaghia. Strabos Geographica reports that in antiquity, the Black Sea was often just called the Sea, for the most part, Graeco-Roman tradition refers to the Black Sea as the Hospitable sea, Εὔξεινος Πόντος Eúxeinos Póntos. This is a euphemism replacing an earlier Inhospitable Sea, Πόντος Ἄξεινος Póntos Áxeinos, strabo thinks that the Black Sea was called inhospitable before Greek colonization because it was difficult to navigate, and because its shores were inhabited by savage tribes. The name was changed to hospitable after the Milesians had colonized the southern shoreline and it is also possible that the epithet Áxeinos arose by popular etymology from a Scythian word axšaina- unlit, dark, the designation Black Sea may thus date from antiquity. A map of Asia dating to 1570, entitled Asiae Nova Descriptio, from Abraham Orteliuss Theatrum Orbis Terrarum, english-language writers of the 18th century often used the name Euxine Sea to refer to the Black Sea

Red Sea
–
The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait, to the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez. The Red Sea is a Global 200 ecoregion, the sea is underlain by the Red Sea Rift which is part of the Great Rift Valley. The Red Sea has an area of roughly 438,000 km2, is about 2250 km long and. It has a depth of 2211 m in the central median trench. However, there are also extensive shallow shelves, noted for their marine life, the sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the worlds northernmost tropical sea, the International Hydrographic Organization defines the limits of the Red Sea as follows, On the North. The Southern limits of the Gulfs of Suez and Aqaba, a line joining Husn Murad and Ras Siyyan. Red Sea is a translation of the Greek Erythra Thalassa, Latin Mare Rubrum, Arabic, البحر الأحمر. Al-Baḥr Al-Aḥmar, Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī, the name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the waters surface. A theory favored by modern scholars is that the name red is referring to the direction south. The basis of this theory is that some Asiatic languages used color words to refer to the cardinal directions, herodotus on one occasion uses Red Sea and Southern Sea interchangeably. Historically, it was known to western geographers as Mare Mecca. Some ancient geographers called the Red Sea the Arabian Gulf or Gulf of Arabia. C, in that version, the Yam Suph is translated as Erythra Thalassa. The Red Sea is one of four seas named in English after common color terms — the others being the Black Sea, the White Sea and the Yellow Sea. The direct rendition of the Greek Erythra thalassa in Latin as Mare Erythraeum refers to the part of the Indian Ocean. The earliest known exploration of the Red Sea was conducted by ancient Egyptians, one such expedition took place around 2500 BC, and another around 1500 BC. Both involved long voyages down the Red Sea, historically, scholars argued whether these trips were possible
